Problems solved by technology

[0002] Due to the characteristics of energy saving, good applicability, short response time, and environmental protection, LED lights have been used in mobile phones, table lamps, home appliances and other daily household appliances and machinery production, but their prices are relatively high. The rapid expansion and prolonging the service life have also become an urgent problem to be solved
[0003] LED lights still have a certain amount of heat during use, and failure to dissipate heat in time is an important reason for shortening the life of LED lights
In order to solve the problem of affecting the luminous efficiency of the lamp and shortening the service life of the lamp due to the heat generated during the use of the lamp, the current method used is to coat a layer of heat dissipation paint on the lamp, but the heat dissipation effect of the existing heat dissipation paint is not very good. Good, the waterproof performance is not good, and it cannot meet the requirements of use in the field of LED lights
